Rent vs Buy Calculator
Compare the total cost of buying a home against renting over the years you'll stay, accounting for the mortgage, upkeep, appreciation, and equity on sale.
Como usar esta calculadora
- 1Enter the home price, your down payment percentage, and the mortgage rate.
- 2Enter the monthly rent for an equivalent place and how many years you'll stay.
- 3Set expected home appreciation and annual rent increases.
- 4Read which option costs less over your stay, and find the break-even year in the table.

Rent vs buy comparison
net buy cost = (down + closing + payments + upkeep) − equity at sale equity at sale = sale value − loan balance − selling costs rent total = Σ rent × 12 × (1 + increase)^year buy if net buy cost < rent total over your stay
The honest comparison is not monthly payment versus monthly rent — it is the total cost of each path over the years you actually stay. Buying front-loads big costs (down payment, closing fees) and adds upkeep, taxes, and interest, but you recover much of it as equity when you sell, boosted by any appreciation. Renting has no upfront outlay and no upkeep, but every dollar is gone and the rent rises each year. Netting the equity you walk away with against everything buying costs, then comparing that to the accumulated rent, reveals which is genuinely cheaper. The answer hinges on how long you stay: the longer the horizon, the more buying's upfront costs are amortised and the more appreciation compounds, which is why there is usually a break-even year before which renting wins.
Exemplo resolvido
On a $400,000 home with 20% down at 6.5%, staying 7 years with 3% appreciation, buying nets out around $145,000 after recovering equity on sale, while renting an equivalent place at $2,000/month rising 3% a year totals about $184,000 — so buying comes out roughly $39,000 ahead over that horizon.

The 'rent is throwing money away' myth
The most repeated argument for buying is that rent is money you never see again, while a mortgage builds equity. There is truth in it, but it hides how much of a mortgage payment is also money you never see again. In the early years of a loan, the large majority of each payment is interest, not principal — interest is just as gone as rent. On top of that, buyers pay property taxes, insurance, maintenance, and thousands in closing and selling costs, none of which builds equity.
A fair comparison counts all of it. When you add up interest, taxes, upkeep, and transaction costs, the amount a buyer 'throws away' can rival or exceed rent for the first several years. What tips the balance toward buying over time is principal paydown and appreciation, both of which take years to accumulate meaningfully. The slogan is not wrong so much as incomplete, and the incomplete version leads people to buy when their timeline makes renting the cheaper choice.
Why your time horizon decides it
The single biggest factor in the rent-versus-buy decision is how long you will stay. Buying carries heavy fixed costs at both ends — roughly 3% of the price to buy and 6% or more to sell. Those costs are spread across however many years you own the home, so a short stay concentrates them into a crushing per-year figure, while a long stay dilutes them. This creates a break-even point: a number of years below which renting is cheaper and above which buying wins.
For typical assumptions the break-even often lands somewhere between three and seven years, though it moves with prices, rates, and appreciation. The practical rule is that if you might move within a few years — a new job, a growing family, uncertainty — renting is usually the safer financial bet even in a 'good market to buy.' The table above shows this directly: watch the year in which the net cost of buying drops below the cumulative rent, and ask honestly whether you will still be in the home by then.
What this model leaves out
No rent-versus-buy calculator captures everything, and it is worth knowing the simplifications. This one assumes steady appreciation, when real house prices lurch and can fall; it approximates taxes and upkeep as a flat percentage of the purchase price rather than tracking them precisely; and, importantly, it does not credit renters with the investment return they could earn on the down payment they never had to make. A renter who invests that lump sum in the market changes the comparison meaningfully.
There are also non-financial factors that no formula can weigh. Owning brings stability, freedom to renovate, and protection from a landlord's decisions, at the cost of flexibility and the burden of repairs. Renting buys mobility and predictable costs, at the cost of building no equity and living with a landlord's rules. Use the number here to understand the financial trade-off clearly, then set it beside the parts of the decision that money cannot measure.
Perguntas frequentes
Is it cheaper to rent or buy?
It depends mostly on how long you stay. Buying has heavy upfront and selling costs that only pay off over time, so short stays favour renting and long stays favour buying. This calculator finds the total cost of each over your horizon and identifies the break-even year.
What is the break-even point for buying?
It is the number of years you must stay for buying to become cheaper than renting, once you account for closing costs, selling costs, upkeep, and equity. For typical assumptions it is often three to seven years; below it, renting usually wins. The table shows where the two lines cross.
Does buying always build wealth?
Not automatically. Early mortgage payments are mostly interest, and buying carries taxes, upkeep, and large transaction costs. Wealth from owning comes from principal paydown and appreciation, which take years to outweigh those costs. In a short stay or a flat market, buying can lose money.
Should I include the down payment's lost investment return?
For a fully rigorous comparison, yes — a renter can invest the down payment they never had to make, and that return offsets some of buying's advantage. This calculator omits it for simplicity, so it slightly favours buying; mentally adjust if you would invest the difference.
